Yes I would have thought if it was bad workmanship the company responsible for the bad workmanship should be footing the bill not Strato.This wasn't your fault so those who caused the issue need to deal with the aftermath. This sounds like more is needed than just having the ceiling painted.
Me first me last and if there's anything left me again. That was one of my nan's sayings.The richer people are, and the more they have already, then the more free stuff they get! Illogical.
